NOTES ON SNAKES COLLECTED IN UPPER ASSAiV. Gl.O 



apical facets were very conspicuous in this species. The maxilla supports 

 two large very compressed sabre-like teeth posteriorly which are fully twice 

 the length of the preceding tooth, and separated from it by a short edentulous 

 interval large enough to support one small tooth. These dental pecnliarities 

 are precisely those laid down by Mr. Boulengor to characterise his genus 

 MacropistJiodon as already pointed out by Annandalo." 



Tropidonot'xs Ktolatus (^Linui^), 

 I collected 159 specimens, all but 20 from Dibrugarh. Of 89 sexed 62 were 

 $9-27 ^ (J. The preponderance of 9 9 over $ $ i^ remarkable, exceeding 

 that already noted with regard to 2\ piscator. In none of these did I see any 

 red ornamentation, the overlapped edges of the scales being always pale blue. 

 Many of these were brought alive, and it is remarkable how its disposition 

 contrasts with that of T. piscator, I have never been bitten by one though I 

 have picked up many haphazard. The flattening of the neck is only seen in 

 some specimens, though many erect their bodies. Some flatten themselves very 

 remarkably, and in so doing reveal the pale blue colouring which is under 

 other circumstances hidden. The breeding events, food, etc., will be best given 

 in tabular form.
